I'm actually not using that feature of the test in my test at all.  I only use this main passing `q` as the first argument so it doesn't sleep, it just exits immediately.  I think the sleep is there to keep this from busy-waiting.  You could have it do that forever and then rely on a test failure to cause it to get torn down?  But I'd rather not change that since it's entirely unrelated to the test I added...
